In one embodiment of the tissue massage devices and methods described herein, a tissue massage device can include a base configured to be grasped in a users hand such that a first surface at a proximal end of the device abuts against the users palm. The device can also include a massage head extending from a second surface of the base that is distal to the first surface, the massage head having a generally convex shape and including a textured non-slip surface formed on a distal portion thereof. The textured non-slip surface can prevent sliding motion between the device and a users skin, thereby causing sliding between subcutaneous fascia and muscle that is therapeutic.
